Went on a telco repair once and first thing I saw when I walked in the utility room at the business was a water leak shooting water all over the telco backboard and everything on it and also all over the electric panels.
Even though the electric panels looked sealed I let them turn off the water first and let the electrician check the electric panels right next to the telco and all the intertwined wiring.
Plus knew the telco side I was working on was probably mostly fine anyways in general and that their phone system was a goner not my problem. So let them know to call their vendor out asap and I would stay to confirm the telco side was dried off and working.
So yes try and keep electric and telco/ communication,data away from pipes or cover it.
